The title compounds, which were excreted by patients suffering from porphyria cutanea tarda or rats poisoned with hexachlorobenzene have been synthesized by the b-oxobilane route. Isocoproporphyrin tetramethyl ester (7a) was prepared from pyrromethanes corresponding to rings DA and BC of the macrocycle, and the de-ethyl analogue (7b) was prepared in a similar fashion; acetylation of the latter followed
